Hi all,
I've been slowly collecting parts for the, eventual, mi16 conversion I have planned for my gti. I've got a set of Catcams 4900528 cams, new oem hydraulic lifters, Catcams vernier pulleys, billet alloy crank pulley, a full rebuild kit (cylinder liners, every gasket, o-rings etc) and am about to purchase a set of Jenvey throttle bodies with an Emerald k6 ecu from pug1off (unless anyone had better suggestions, ecu or itb brand??).
My main question is surrounding upping compression to at least 10.8/1. From what I've read the best way to do this is to deck the block and liners 1.3mm roughly to gain this figure. Has anyone done this themselves as no engine shop I've spoken to wants to remove so much material and more pressingly, I can't find a shop that can correctly clamp the liners to reduce their stack height respectively (my only thought is to turn them down on a lathe but that seems a touch dodgy). Are there any of the shelf high comp piston/con-rod setups, other than going forged internals or the Wossner high comp setup which I have been strongly advised against with the obnoxiously high dome design? I've got a figure of 200hp which might be optimistic at 7k rpm if anyone had input on that aswell.
The less pressing question is about the engine loom wiring. Most people seem to splice an mi16 loom into a gti loom but with the addition of ITB's and standalone ecu in the mix I presume a full custom loom is the way to go. Has anybody purchased one from a company or individual that they could recommend as it's not something I would preferably do myself. Or even if there was a wiring diagram out there for a baseline I can start with.
I'm located in AUS so specifically knowledgeable machine shops are hard to come by and used parts from the uk are often out of the question. Apologies if there are threads out there on this topic already that I have blindly missed, I just couldn't find one that answered my questions exactly. Any other input on must have parts or things to avoid while building the engine would be tremendously appreciated. Thanks in advance,
Tom
